Description of the Related Art One of the means for saving labor in agricultural work is the division of labor between seedling and cultivation, that is, a cultivation farmer purchases and grows a large number of seedlings and increased seedlings in a mechanized seedling facility. The method of doing it is developing rapidly. In such a system, a system that uses standardized trays and mass-produces uniform seedlings grown to a size where root mortars are formed in a highly mechanized seedling production facility is called a seedling production system. The seedlings produced there are generally called cell molded seedlings.

First, the growth inhibitor of the present invention will be described. The active ingredient of the growth inhibitor of the present invention is an emulsifier selected from the group consisting of polyhydric alcohol fatty acid esters and lecithin. An emulsifier generally has a lipophilic group and a hydrophilic group in one molecule, and its functional characteristics are generally represented by an HLB value. From the viewpoint of effective activity, a hydrophilic emulsifier having an HLB of 3 or more is more preferable than an oil-soluble emulsifier having a low HLB.

ど）に従って実測が可能である。The HLB value can be calculated by the Atlas equation. The Atlas formula is calculated by HLB = 20 × (1-saponification value / neutralization value) (Koshobo Toru Hidaka, “Emulsifier for food, 2nd edition”). On the other hand, the saponification value is obtained by calculating mg of potassium hydroxide consumed when 1 g of a fatty acid ester of a polyhydric alcohol is hydrolyzed with potassium hydroxide.
The number and neutralization value are mg of potassium hydroxide required to neutralize 1 g of the constituent fatty acids of the fatty acid ester of polyhydric alcohol.
These are numbers, and can be respectively measured according to the calculation from the structural formula of the fatty acid ester of the polyhydric alcohol, or according to a general method of analyzing fats and oils (such as a handbook of fat and oil chemistry edited by Maruzen Co., Ltd.
